Abstract
RATIONALE The use of long-term noninvasive respiratory support is increasing in children along with an extension of indications, in particular in children with central nervous system (CNS) disorders. OBJECTIVE The aim of this study was to describe the characteristics of children with CNS disorders treated with long-term noninvasive respiratory support in France. METHODS Data were collected from 27 French pediatric university centers through an anonymous questionnaire filled for every child treated with noninvasive ventilatory support ≥3 months on 1st June 2019. MAIN RESULTS The data of 182 patients (55% boys, median age: 10.2 [5.4;14.8] years old [range: 0.3-25]) were collected: 35 (19%) patients had nontumoral spinal cord injury, 22 (12%) CNS tumors, 63 (35%) multiple disabilities, 26 (14%) central alveolar hypoventilation and 36 (20%) other CNS disorders. Seventy five percent of the patients were treated with noninvasive ventilation (NIV) and 25% with continuous positive airway pressure (CPAP). The main investigations performed before CPAP/NIV initiation were nocturnal gas exchange recordings, alone or coupled with poly(somno)graphy (in 29% and 34% of the patients, respectively). CPAP/NIV was started in an acute setting in 10% of the patients. Median adherence was 8 [6;10] hours/night, with 12% of patients using treatment <4 h/day. Nasal mask was the most common interface (70%). Airway clearance techniques were used by 31% of patients. CONCLUSION CPAP/NIV may be a therapeutic option in children with CNS disorders. Future studies should assess treatment efficacy and patient reported outcome measures.

Abstract
BACKGROUND Around 20% of people with cystic fibrosis (pwCF) do not have access to the triple combination elexacaftor/tezacaftor/ivacaftor (ETI) in Europe because they do not carry the F508del allele on the CF transmembrane conductance regulator (CFTR) gene. Considering that pwCF carrying rare variants may benefit from ETI, including variants already validated by the US Food and Drug Administration (FDA), a compassionate use programme was launched in France. PwCF were invited to undergo a nasal brushing to investigate whether the pharmacological rescue of CFTR activity by ETI in human nasal epithelial cell (HNEC) cultures was predictive of the clinical response. METHODS CFTR activity correction was studied by short-circuit current in HNEC cultures at basal state (dimethyl sulfoxide (DMSO)) and after ETI incubation and expressed as percentage of normal (wild-type (WT)) CFTR activity after sequential addition of forskolin and Inh-172 (ΔI ETI/DMSO%WT). RESULTS 11 pwCF carried variants eligible for ETI according to the FDA label and 28 carried variants not listed by the FDA. ETI significantly increased CFTR activity of FDA-approved CFTR variants (I601F, G85E, S492F, M1101K, R347P, R74W;V201M;D1270N and H1085R). We point out ETI correction of non-FDA-approved variants, including N1303K, R334W, R1066C, Q552P and terminal splicing variants (4374+1G>A and 4096-3C>G). ΔI ETI/DMSO%WT was significantly correlated to change in percentage predicted forced expiratory volume in 1 s and sweat chloride concentration (p<0.0001 for both). G85E, R74W;V201M;D1270N, Q552P and M1101K were rescued more efficiently by other CFTR modulator combinations than ETI. CONCLUSIONS Primary nasal epithelial cells hold promise for expanding the prescription of CFTR modulators in pwCF carrying rare mutants. Additional variants should be discussed for ETI indication.

Abstract
Background Airway clearance techniques are supposed to be a necessary adjunct for the enhancement of impaired peripheral clearance in cystic fibrosis (CF). The objective was to assess the effect of one physiotherapy session (autogenic drainage: AD) on mucus clearance (sputum wet weight) and impulse oscillometry system (IOS) indices, including those obtained from extended Resistance-Inertance-Compliance (eRIC) modelling, considering the degree of bronchial congestion. Methods Thirty children with CF (median age: 12.7 years) in a stable condition prospectively underwent IOS measurements at baseline and after AD. They were divided in two groups: with (visual analog scale of bronchial congestion by the physiotherapist ≥ 5/10) and without (scale < 5/10) bronchial congestion. Paired-comparison of the effects of AD on airway resistance measurements was done with Wilcoxon test. Results The congestion scale correlated with the wet weight of sputum production during the session (Pearson test: p < 0.0001, R = 0.66). Ten children had bronchial congestion and 20 were without congestion. In the whole group, R5–20 Hz significantly decreased after AD (P = 0.049), which was related to a decrease in the children with congestion (P = 0.025), whereas it was not significantly modified in the children without congestion (P = 0.327). The eRIC model allowed the calculation of the peripheral resistance of the respiratory system, which also decreased in the children with congestion (P = 0.037), however, not modified in the children without congestion (P = 0.390). Conclusion One session of autogenic drainage has the ability to decrease peripheral resistance obtained from IOS measurements, more specifically in children with CF with moderate to severe bronchial congestion. Trial registration ClinicalTrials.gov Identifier: NCT04094441.

Abstract
The objective of our cross-sectional study was to assess the relationships between indices of multiple breath washout (MBW) and impulse oscillometry system (IOS) in cystic fibrosis in forty consecutive children (median age 8.1 years) in stable conditions and to evaluate whether cut-off values of IOS indices may help to avoid MBW, which is time-consuming. IOS measurements took a median duration of 3 min, while MBW measurements took a median duration of 49 min. Lung Clearance Index (LCI2.5% ) depicted significant linear correlations with z-scores of R5Hz, R5-20Hz, X5Hz, AX, and Fres (r2 = 0.27 to 0.51). Receiver-operator characteristic curves were constructed and showed that the best compromise was obtained with the z-score of Fres, with a cut-off value of -1.37 that had a sensitivity of 0.966, a specificity of 0.636, and a negative predictive value of 0.875. This z-score is useful for excluding increased LCI2.5% when below -1.37 using the reference set of Gochicoa et al. In conclusion, IOS measurement is easily and rapidly obtained in children and may be clinically useful for excluding increased LCI2.5% , thus allowing the time-consuming MBW test to be avoided.

Abstract
OBJECTIVE To describe the characteristics of children treated with long term continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) in France. DESIGN Cross-sectional national survey. SETTING Paediatric CPAP/NIV teams of 28 tertiary university hospitals in France. PATIENTS Children aged <20 years treated with CPAP/NIV since at least 3 months on June 1st, 2019. INTERVENTION An anonymous questionnaire was filled in for every patient. RESULTS The data of 1447 patients (60% boys), mean age 9.8 ± 5.8 years were analysed. The most frequent underlying disorders were: upper airway obstruction (46%), neuromuscular disease (28%), disorder of the central nervous system (13%), cardiorespiratory disorder (7%), and congenital bone disease (4%). Forty-five percent of the patients were treated with CPAP and 55% with NIV. Treatment was initiated electively for 92% of children, while 8% started during an acute illness. A poly(somno)graphy (P(S)G) was performed prior to treatment initiation in 26%, 36% had a P(S)G with transcutaneous carbon dioxide monitoring (PtcCO2), while 23% had only a pulse oximetry (SpO2) with PtcCO2 recording. The decision of CPAP/NIV initiation during an elective setting was based on the apnea-hypopnea index (AHI) in 41% of patients, SpO2 and PtcCO2 in 25% of patients, and AHI with PtcCO2 in 25% of patients. Objective adherence was excellent with a mean use of 7.6 ± 3.2 h/night. Duration of CPAP/NIV was 2.7 ± 2.9 years at the time of the survey. CONCLUSION This survey shows the large number of children treated with long term CPAP/NIV in France with numerous children having disorders other than neuromuscular diseases.

Abstract
Mutations in the perforin gene cause familial hemophagocytic lymphohistiocytosis (FHL). The first symptoms of FHL are usually intractable fever, hepatosplenomegaly, and pancytopenia. Most FHL patients subsequently develop central nervous system (CNS) manifestations due to infiltration of tissues by activated lymphocytes and macrophages. We report 2 FHL patients with an atypical phenotype characterized by isolated severe neurologic symptoms mimicking chronic encephalitis and leading to an early death. Functional and molecular analyses revealed the same novel missense mutation in the perforin gene in both patients; this mutation affected the calcium-binding domain of the protein. This missense mutation did not affect perforin maturation or expression in cytotoxic cells but impaired in vitro cytotoxic activity. Diagnosis was delayed in both patients because of the initial neurologic expression and the normal expression of perforin in circulating lymphocytes. This emphasizes the importance of early diagnosis of this atypical form of FHL, as CNS involvement causes severe, irreversible encephalopathy. This observation also raises the question of the role of some mutations in the neurologic expression of FHL.

Abstract
STUDY OBJECTIVE To determine the cell profile of BAL from infants with severe recurrent wheezing who were not acutely ill at the time of investigation, suggesting an ongoing inflammation. DESIGN AND PATIENTS In a retrospective study, we determined BAL cell profiles for 83 children with wheezing aged 4 to 32 months (mean +/- SD, 11.3 +/- 5.5 months). Fiberoptic bronchoscopy was performed in children with severe recurrent wheezy bronchitis unresponsive to inhaled steroids. These children were compared with 17 children aged 6 to 36 months (mean, 15.1 +/- 7.5 months) with various nonwheezing pulmonary diseases. Children were included as control subjects if they had no endobronchial inflammation and no atopy. RESULTS The BAL cell profile of young children with wheezing typically includes a significantly higher cell count (mean, 644.4 +/- 956.8 x 10(3)/mL vs 313 +/- 203.2 x 10(3)/mL, p = 0.008), a significantly higher percentage of neutrophils (mean, 9 +/- 12.1% vs 2.1 +/- 2.2%, p = 0.003), and a higher neutrophil count (mean, 43.2 +/- 81.6 x 10(3)/mL vs 7.9 +/- 11.8 x 10(3)/mL, p = 0.003), as compared with control subjects. The larger number of neutrophils in children with wheezing was not correlated with bacterial or viral infection, or with age, sex, or atopic status. In contrast to the situation in asthmatic adults, eosinophil levels were not higher in children with wheezing than in control subjects (mean, 0.09 +/- 0.27% vs 0.08 +/- 0.25%). CONCLUSION Neutrophil-mediated inflammation in the airways appears to better characterize severe recurrent wheezing in children < 3 years old.

Abstract
Asthma is the most frequent chronic disease in pediatrics and the increase in its prevalence is a major public health problem. Diagnosis may be difficult in the young child, symptomatology most often occurring following a viral infection. It is important not to ignore a foreign body in the airways or fibrocystic disease and asthma remains, particularly in infants, a diagnosis of elimination. Misdiagnosis or insufficient treatment of asthma may risk the development of irreversible histological lesions and also could compromise pulmonary growth and the child's lung reserve. Spacer devices and nebulisers enable inhaled therapy to be administered to very young children. The value of early diagnosis is to institute appropriate treatment notably in severe asthma with inhaled corticosteroid therapy, the aim being to reduce remodelling lesions of the airways. The minimal effective dose should be defined to minimalise side-effects. The treatment of asthma is not restricted to pharmacotherapy: attempts should be made to reduce intercurrent viral infections, domestic pollution (including smoking) and allergenic concentrations. However, as for all chronic diseases, the clinician will encounter poor compliance. The work of education and support of health professionals is fundamental to the management of asthma.
